Two members of the anti-Kremlin punk band Pussy Riot have been sent to remote prison camps to serve their sentences, the group has said.

Maria Alyokhina, 24, will serve the rest of her two-year term at a women's prison camp in Perm, a Siberian region notorious for hosting some of the Soviet Union's harshest camps. Nadezhda Tolokonnikova, 22, has been sent to Mordovia, a region that also hosts a high number of prisons.
